A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in 2022.

Keeping abreast of the antimicrobial stewardship-related articles published each year is challenging. The Southeastern Research Group Endeavor identified antimicrobial stewardship-related, peer-reviewed literature that detailed an actionable intervention during 2022. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight actionable interventions used by antimicrobial stewardship programs to capture potentially effective strategies for local implementation.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications for Hospitalized Patients in 2021.

Keeping abreast of the antimicrobial stewardship-related articles published each year is challenging. The Southeastern Research Group Endeavor (SERGE-45) identified antimicrobial stewardship-related, peer-reviewed literature that detailed an "actionable" intervention among hospitalized populations during 2021. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight "actionable" interventions used by antimicrobial stewardship programs in hospitalized populations to capture potentially effective strategies for local implementation.

A retrospective cohort study of the effect of rapid versus delayed-result procalcitonin testing on antibiotic use at a community hospital.

BACKGROUND: Procalcitonin is a serum biomarker used to distinguish bacterial infection from viral or noninfectious syndromes. Primary literature shows mixed data on use of procalcitonin for de-escalation of antimicrobials. Delays in test results of send-out procalcitonin assays may result in prolonged antimicrobial durations. It is unknown whether availability of rapid-result assays may shorten time to antibiotic de-escalation. AIM: This retrospective, cohort study compared antibiotic durations of treatment between groups with rapid-result versus delayed send-out, procalcitonin test modality. This study was exempt from Ethics Committee Approval, as determined by the Institutional Review Board at the study site. METHOD: Adult hospitalized patients were included if they had at least one procalcitonin test performed during the study period. The primary outcome compared mean duration of antimicrobial therapy between groups receiving a rapid-result procalcitonin test and a send-out test. Secondary outcomes included incidence of Clostridiodes difficile infection, mention of procalcitonin testing in the electronic medical record in reference to antimicrobial therapy decision making, and presence of comorbidities which affect procalcitonin levels independent of infection. RESULTS: A total of 350 lab results were analyzed. The duration of antimicrobial treatment between groups was not statistically different with the median duration of treatment in the send-out group being 2.95 days compared to 3.35 in the rapid result group, p = 0.856. Patient comorbidities with potential to lead to a noninfectious elevation or falsely high level of procalcitonin were common. CONCLUSION: Use of a rapid-result procalcitonin assay does not reduce hospital antimicrobial therapy duration as compared with send-out testing.

Effects of an automatic discontinuation of antibiotics policy: A novel approach to antimicrobial stewardship.

PURPOSE: A novel automatic discontinuation policy implemented within an antimicrobial stewardship program (ASP) is described, and results of an evaluation of the policy's effects on antibiotic usage are reported. METHODS: A retrospective, before-and-after study was conducted at an 800-bed, tertiary care, academic teaching hospital to evaluate selected antibiotic usage outcomes in both intensive care unit (ICU) and non-ICU adult patients targeted for ASP interventions before and after implementation of an automatic discontinuation of antibiotics policy (ADAP) authorizing the ASP team to automatically halt antibiotic therapy in cases involving inappropriate duplicate antimicrobial coverage or excess duration of therapy. The primary outcome was total days of antibiotic therapy. Secondary outcomes included excess days of therapy and rates of 30-day readmission, Clostridioides difficile infection, and multidrug-resistant infection. RESULTS: There were no statistically significant differences in group demographics or clinical characteristics. The most common indication for antibiotics was hospital-acquired pneumonia, and the most common reason for ASP intervention was excess duration of therapy. The mean total number of antibiotic days per patient was reduced from 7.6 days in the pre-ADAP group to 6.6 days in the post-ADAP group (p < 0.05). The mean number of excess days of antibiotics was similarly reduced, from 2.3 days to 1.5 days, after implementation of the ADAP (p < 0.05). CONCLUSION: Adoption of an ADAP-a more active approach to ASP interventions-was effective in reducing overall antibiotic usage and improving the efficiency of the ASP.

Implementation and assessment of a pulmonary diseases elective course for third-year pharmacy students.

BACKGROUND: Given the significant public health burden of pulmonary diseases and the vital role pharmacists play in management across the continuum of care (and within transitions in care), an elective course for pharmacy students focused on pulmonary diseases was developed. EDUCATIONAL ACTIVITY: A month-long elective course for third-year pharmacy students consisting of 12 class sessions delivered in two-hour periods three times per week, was implemented. The course was delivered using the team-based learning (TBL) format in addition to hands-on skills and simulation sessions. Knowledge and skills assessments were administered before and after completion of the course. Student perceptions of self-confidence and ability regarding management of pulmonary diseases pre- and post-course and their perceptions of the course and TBL as a teaching strategy for this course were evaluated upon course completion. CRITICAL ANALYSIS: Nine students completed the course. Mean scores on knowledge and skills assessment significantly improved after completion of the course (54.5% pre-course vs. 79.3% post-course; p < 0.05% and 60.3% pre-course vs. 93.2% post-course; p < 0.05, respectively). Student perceptions of their ability to care for patients with pulmonary diseases significantly increased, compared to pre-assessments, in all areas taught in the course (p< 0.05). Additionally, students' confidence in managing specific disease states significantly improved in all areas (p < 0.05) except for spirometry (p = 0.06). Students' knowledge, skills, and confidence regarding management of common pulmonary disease states improved following this month-long elective course delivered using a combination of TBL activities and hands-on skills sessions.

A multidimensional antimicrobial stewardship intervention targeting aztreonam use in patients with a reported penicillin allergy.

BACKGROUND: Local antimicrobial susceptibility patterns should be considered for antimicrobial therapy decisions. Antibiogram data can guide beta-lactam antibiotic use in the presence of a penicillin allergy, particularly when allergic cross-reactivity among antibiotic agents is unlikely. OBJECTIVE: To evaluate the effect of a multidimensional antimicrobial stewardship intervention to improve antibiogram-driven antibiotic selection for patients with a reported penicillin allergy receiving aztreonam. METHODS: This historically controlled, quasi-experimental study compared historical aztreonam use with prospective antibiotic selection following a pharmacist-led intervention in patients with a penicillin allergy. The impact of this intervention on aztreonam use, antimicrobial selection, patient allergy profile updates, length of stay, in-hospital mortality, and antibiotic cost savings was assessed. RESULTS: A significant reduction in median days of aztreonam therapy (4.0 vs. 2.0; p = 0.0001) and median days of therapy per 1000 patient days (14.5 vs. 9.3; p = 0.0001) was found in the intervention group. CONCLUSION: A pharmacist-led antimicrobial stewardship intervention facilitated antibiogram-driven antibiotic therapy while reducing aztreonam use in patients without an anaphylactic penicillin allergy. Further trials are needed to assess the utility of similar antimicrobial stewardship interventions for patients with penicillin allergy.
